Unequal loss protection scheme using a quality prediction model in a Wi-Fi broadcasting system

Wireless local area network–based broadcasting techniques are a type of mobile Internet Protocol television technology that simultaneously transmits multimedia content to local users. Contrary to the existing wireless local area network– based multimedia transmission systems, which transmit multimedia data to users using unicast packets, a wireless local area network–based broadcasting system is able to transmit […]

Analysis of Characteristics of Video Quality for Unequal Loss Protection in Wi-Fi based Broadcasting System

The Wi-Fi based broadcasting system using broadcast packets not the unicast packets of WLAN aims to provide the same quality of multimedia streaming to increased numbers of users. However, for the broadcasting packet without MAC level retransmission, packet loss is unavoidable and the place where the loss of broadcast packet occurs is not predictable. Therefore, […]

Analysis of broadcast packet loss for unequal loss protection in Wi-Fi broadcasting system

Wi-Fi broadcasting system is to offer multimedia streaming of the same quality to users even with increasing numbers of users by using broadcasting packet, not Unicast packet. However, the broadcast packet has high packet loss rate because it has not retransmission Medium Access Control (MAC) to recover the packet loss. Therefore, to prevent service quality […]
